WALL CONSTRUCTION.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application filed July 24, 1916. Serial No. 111,065.

To all whom it may concern:

Be it known that 1, PAUL KOSACK, a citizen of the United States,residing at Grand Island, in the county of Hall and State of Nebraska,have invented certain new and useful Improvements in \Vall Construction,of which the following is a specification.

This invention relates to an improvement in wall construction forbuildings, and has for its principal object to provide such aconstruction that rectangular wall blocks having greater attenuationthan the'ordinary ones, may be used for the several courses, the blocksof the courses to be secured transversely of the wall at uniformdistances from each other, and the courses to be maintained in verticalalinement until the space between the courses has been filled withcement or other similar adhesive material to form a wall of unusualsolidity. The invention includes the use of wall ties constructed ofwire so that manufacture will be economical, and the use of T-barsadapted to be disposed vertically between the connected wires of thewall ties in a manner to maintain the blocks of the courses in verticalalinement. The invention also has reference to the formationof recessesin the wall blocks so that the wall ties will not be visible.

With the foregoing objects in view the invention presents a novelconstruction, combination and arrangement of parts as describedhereinand claimed, and as illustrated in the accompanying drawing, wherein,-

Figure 1 is a plan view,'broken away and showing a wall constructed inaccordance with the invention. Fig. 2 is a broken away view on anenlarged scale, being a transverse section on line 2 2 of Fig. 1, a bodyof cement being added and shown in ection. Fig. 3 is an end view of oneof the wall ties. Figs. 4 and 5, respectively, are broken away sideviews of T-bars.

Referring now to the drawing, numerals 6 indicate the outer blocks of awall, each being formed, preferably, with an ornamental face a, theblocks for the inner side of the wall being indicated at 7, and eachwall block is provided. to open upon its respective up or and lower sidewith recesses 8 and 8'. Xt 9 are indicated wall ties, each beingconstructed of a pair of wire strands of substantially the same length.each being bent to form a spiral part' a, midway between its ends, andcurved adjacent to the spiral part to provide an outwardly divergentpart b and a pair of outwardly pro jecting parallel arms 0 and 0' withopposed transverse terminal loops or hooks d and d, and to provide foreach arm a a terminal transverse holder-arm c, said strands beingdisposed with the spiral parts a in enga ement or in intertwinedrelation and there y providing a pair of inwardly convergent recesses 10between their armsa and out wardly divergent parts I).

When the blocks 6 and 7 are laid to form wall courses, the wall ties 9are disposed on the upper side of the blocks, the loops or books dengaging in the recesses 8 of said blocks, the arms 0 engaging the innersides of the blocks, said arms operating to main 'tain the blocks 6 and7 of a course at uniform distances apart. After the wall ties 9 havebeen placed in the position indicated the T-bars are inserted verticallyin recesses v10 in engagement with the inner sides of said blocks, theirfunction being to maintain the courses in vertical alinement. Cement 12or similar adhesive material in plastic or semi-plastic form is thendeposited between the courses. It soon becomes hardened and the wallthus formed will provide unusual solidity. At the time of laying thecourses the hooks or loops d will engage in recesses 8' of the blocks 6and 7.

As described, the function to be discharged by the hooks or loops d andd in conjunction with the respective .recesses 8 and 8 is to prevent anyoutward movement of the blocks of a course and on account of theconstruction the walls may have such thickness as may be desired withoutchanging the thickness of the blocks, the wall ties 9 being changed insize and proportion to correspond to such requirements, the importantfeature in this respect being that the holders e Will,bear upon theinner sides of the blocks.

Any suitable arrangement may be made of wire strands for a corner walltie 13, the parts shown in Fig. 1 for this purpose being the strands 14,15 and 16, these being bent spirally and assembled to provide terminalloops or hooks for engaging in recesses 17 of the blocks and to provideholder arms 18 for bearings upon the inner sides of the blocks, and. toprovide recesses 10 within which the T-bars 11 may be verticallydisposed, the function to be discharged by these parts beingsubstantially the same as already described.

Among some of the advantages to be derived by use of the invention, itmay be stated that the wire hooks or loops are not visible from theoutside of the wall since they are anchored in the recesses of the wallblocks.- The wall ties, since they consist of wire strands, may be veryeconomically manufactured, and the T-bars on account of their shaperesist stresses to advantage and since they are of metallic constructlonthey will not be injured by contact with the cement which is depositedbetween the blocks of the courses.

Having fully described my invention what I claim and desire to secure byLetters Patent is, s

In wall construction, the combination of rectangular wall blocksdisposed in courses, each block being provided with recesses between itsouter and inner faces to'open on its.uppe1- and lower sides, a pluralityof wall ties, each consisting of a pair of metallic strands, each strandbeing bent to' provide a spiral part midway between its ends, divergentparts outwardly of the spiral part, a pair of adjacent parallel armswith transversely disposed terminals outwardly of the divergent partsand a pair of holder-arms, disposed inwardly of the loops at rightangles to said parallel arms, said metallic strands having their spiralparts disposed in intertwined relation with their divergent parts andparallel arms adjaccntto each other to provide a pair of recesses, saidwall ties being adapt ed to be disposed between the wall blocks of alower and upper course with the transversely disposed terminals of saidparallel arms disposed in the recesses of said blocks,

their holder-arms engaging the inner sides of the wall blocks, and aplurality of T-bars, each being disposed vertically in the recesses ofsaid wall ties inengagement with the wall blocks of an upper and lowercourse. In testimony whereof, I have affixed my signature in presence oftwo witnesses.
